CVE-2026-78677

GitPython before 3.1.59 Path Traversal via separate-git-dir

Published Aug 25, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
GitPython before 3.1.59 omits --separate-git-dir from unsafe_git_clone_options, allowing attackers to create arbitrary git directories outside the intended clone destination. Attackers can pass a separate_git_dir parameter to Repo.clone_from() or Repo.clone() to redirect repository metadata to an attacker-controlled filesystem path, enabling arbitrary directory creation and potential hook execution.
